完整的ESA火星快车任务观测元数据目录——这是运行时间最长、科学成果最丰富的火星轨道器之一。火星快车于2003年12月进入火星轨道，携带了8种仪器：HRSC（高分辨率立体相机）、MARSIS（地下雷达探测器）、OMEGA（矿物学光谱仪）、PFS（行星傅里叶光谱仪）、SPICAM（紫外/红外光谱仪）、ASPERA-3（等离子体分析仪）、MaRS（无线电科学实验）和VMC（视觉监测相机）。该数据集包含来自ESA行星科学档案（PSA）的完整观测元数据，符合EPN-TAP标准。每一行代表一个观测或数据块，包含时间、空间覆盖范围、仪器参数和访问URL。HRSC生成了最完整的高分辨率立体地形图，MARSIS检测到与南极层状沉积物下液态水一致的反射信号，OMEGA绘制了包括层状硅酸盐和硫酸盐在内的全球矿物分布图，约束了气候历史。20多年的时间基线捕捉了多个完整的火星年的大气监测、季节性极冠演化、沙尘暴周期和地表变化。该数据集适用于表格分类任务。

Complete observation metadata catalog from the ESA Mars Express mission -- one of the longest-running and most scientifically productive Mars orbiters. Mars Express entered Mars orbit in December 2003 and carries a suite of 8 instruments: HRSC (high-resolution stereo camera), MARSIS (subsurface radar sounder), OMEGA (mineralogy spectrometer), PFS (planetary Fourier spectrometer), SPICAM (UV/IR spectrometer), ASPERA-3 (plasma analyzer), MaRS (radio science experiment), and VMC (visual monitoring camera). This dataset contains the full observation metadata from the ESA Planetary Science Archive (PSA), conforming to the EPN-TAP standard. Each row represents one observation or data granule, with timing, spatial coverage, instrument parameters, and access URLs. HRSC has produced the most complete high-resolution stereo topographic map of Mars. MARSIS detected reflections consistent with liquid water beneath the south polar layered deposits. OMEGA mapped global mineralogy including phyllosilicates and sulfates constraining climatic history. The 20+ year temporal baseline captures multiple complete Martian years of atmospheric monitoring, seasonal polar cap evolution, dust storm cycles, and surface changes. This dataset is suitable for tabular classification tasks.
